"I am in serious trouble. You can help me. I've had a shock to-day--a grievous shock." He stopped and tried to pull himself together. "I must trust you implicitly, Mr. Acton, I have no choice. Tell me what you think of this." He drew a case from his breast pocket and opened it. "I promised you should see the Valdez sapphire. Look there!" The Valdez sapphire! A great big shining lump of blue crystal--flawless and of perfect color--that was all. I took it up, breathed on it, drew out my magnifier, looked at it in one light and another. What was wrong with it? I could not say. Nine experts out of ten would undoubtedly have pronounced the stone genuine. I, by virtue of some mysterious instinct that has hitherto always guided me aright, was the unlucky tenth. I looked at the bishop. His eyes met mine. There was no need of spoken word between us. "Has Lady Carwitchet shown you her sapphire?" was his most unexpected question. "She has? Now, Mr. Acton, on your honor as a connoisseur and a gentleman, which of the two is the Valdez?" "Not this one." I could say naught else. "You were my last hope." He broke off, and dropped his face on his folded arms with a groan that shook the table on which he rested, while I stood dismayed at myself for having let so hasty a judgment escape me. He lifted a ghastly countenance to me. "She vowed she would see me ruined and disgraced. I made her my enemy by crossing some of her schemes once, and she never forgives. She will keep her word. I shall appear before the world as a fraudulent trustee. I can neither produce the valuable confided to my charge nor make the loss good. I have only an incredible story to tell," he dropped his head and groaned again. "Who will believe me?" "I will, for one." "Ah, you? Yes, you know her. She took my wife from me, Mr. Acton. Heaven only knows what the hold was that she had over poor Mira. She encouraged her to set me at defiance and eventually to leave me. She was answerable for all the scandalous folly and extravagance of poor Mira's life in Paris--spare me the telling of the story. She left her at last to die alone and uncared for. I reached my wife to find her dying of a fever from which Lady Carwitchet and her crew had fled. She was raving in delirium, and died without recognizing me. Some trouble she had been in which I must never know oppressed her. At the very last she roused from a long stupor and spoke to the nurse. 'Tell him to get the sapphire back--she stole it. She has robbed my child.' Those were her last words. The nurse understood no English, and treated them as wandering; but _I_ heard them, and knew she was sane when she spoke." "What did you do?"
